Got error E: Package 'apache2' has no installation candidate while installing apache2 with sudo apt-get install apache2 on Ubuntu 17.10. Here is the message displayed on terminal.

sudo apt-get install apache2
Reading package lists... Done

This may mean that the package is missing, has been obsoleted, or
is only available from another source

How can I solve this issue?

Solution 1

The main problem is missed /etc/apt/sources.list. You can recreate it with:

cat <<EOF | sudo tee /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu $(lsb_release -cs) main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu $(lsb_release -cs)-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu $(lsb_release -cs)-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu $(lsb_release -cs)-backports main universe restricted multiverse
EOF

Then run

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install apache2

Solution 2

Try sudo apt-get update and then sudo apt-get install apache2. I recommend installing the complete LAMP Stack using tasksel

sudo apt-get install tasksel

sudo tasksel to launch it Select LAMP server and install it. Hope that helps.

Please edit your question and add output of apt-cache policy apache2 to it.

[pomsky]

Also please add the contents of your /etc/apt/sources.list file.

[Kiran Shahi]

inside /etc/apt/ there is no sources.list file

[N0rbert]

Please add output of egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*.list to the question.

The install command is sudo apt update && sudo apt install apache2

Possible duplicate of Trying to install apache.But, when I type in the command it shows this error. Could anyone give me any solution, tried everything

[Kiran Shahi]

@N0rbert I have updated output of the command you have mentioned.

[Kiran Shahi]

Thank you for your answer. But I need to install LAMP manually.

A note for future internet searchers who may come across this answer: if you're using a version other than 17.10, replace "artful" with your version's name (rather than copy/pasting the whole thing directly into your terminal as I did.)

[N0rbert]

@Ilak thanks for idea, I edited the answer to make it universal.
